\ IMPROVEMENT IN GHURNS.

TO ALL WHOM IT MAY CONCERN:

Be it known'that I, J. B. SWEETLAND, of Pontiac, in the county ot' Oakland, and State of Michigan, have invented certain new and useful Improvements in Churns; and I do hereby declare that the following is a full,

clear, and exact description of the same, reference being' had to the accompanying drawings and to the letters of reference marked thereon.

In the annexed drawings, tmaking part of this specification, A represents the body of the churn, which is a square box with a concave bottom. The bottom is either formed of staves or slats,or is made of one piece'of wood curved in the proper manner. The body A is supported upon four legs. B represents a shaft which passes thro'ugh thc churn-box from its two ends; this shaft is provided with two sets of wings or das-hers, C C, i

which are placed or secured upon `the shaft at such an angle that, when th shaft is rotated in the direction it is'intendcd to move, they force the cream or milk toward each other. The wings are placed near the ends of t Y the box, and so adjusted that their ends as they revolve will scrape the cream from the ends of the box. The t shaft B is confined in position in the chui-mbox by means of la screw, H, at one end, and a short shaft, a, at the other, both of which pass through the ends of the box and into the ends of the .said shaft. The shaft a isprovided on its outer end with a pinion, I, into which gears a. toothed wheel, J. The wheelJ is secured upon a short axle, K, which passes into the end of the box, as shown. L represents a spring bent asshown, and pivoted atl one end to the end of the box; the other end fits into alittle recess in the outer face of the pinion I, and serves to keep the pinion in its place. By springing out this spring L and swinging it out of the'way, the pinI ion may be removed. By taking out the` screw H, the shaft B may then be removed fronrthe box.' D represents the cover of the box or body A. This cover fits down into the mouth of the box.. A square or oblong opening is cut through the centre of the top; and on the under` side osaid top two bars or cleats are nailed or secured.

Thesev cleats or bars are marked e e, and are provided with grooves, into which grooves a `paneof glass or door,

G, is slipped. flhe lglass G is about `a quarter or half an inch below the cover D, and projects about threeeighths of an inch beyond the sides of 4the opening cut in the cover D. The object of this arrangement is to allow of ventilation or a free circulation of air through the churn-box, without danger of `the cream or milk splashing-out. It will be seen that the construction of the dasher-shaft and its suppprts is suchv that said dasher can `be easily removed for gathering thel butter or for cleansing the churn, or any other desirable purpose. I

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The cover D, provided with the Ventilating door G, dropped below the opening cut `through said cover, i whereby a free circulation of air is had to and from the churn-boxaround the sides of the door, used in comi .bination with the churn-box, dasher-shaft, screw H, shaft a, pinion I, and spring L; the whole being arranged i.

in the manner substantially as speciied. y v

As evidence that I claim the foregoing, I have hereunto set my hand, in the presence of two witnesses.
